Does the 2007 Toyota Yaris have anti lock brakes?

The 2007 Toyota Yaris had the option for anti-lock brakes, but it was not featured as standard equipment until the 2009 model year. If ABS was what You needed in 2007, You would have needed to go with the "power package" on the Sedan or S Sedan. A number of years later, it can be difficult to trace which packages were equipped on the Yaris when new, so there's an easier way to check. Pop Your hook, and check Your brake master cylinder. Follow the brake lines coming off of it, and if You eventually see a box (typically black) with four steel lines coming from it, then You'll be equipped with ABS. Alternatively, You can wait for it to break (which it usually does) and look for the dash light :)
